STAMPING AND NUMBERING MACHINE.

SPECIFICATION forming part of Letters Patent No. 660,512. dated October 23, 1900.

Application filed June 15.1898.

T aZZ whom it may concern:

Be it known that we, JAMES D. HUMPHREY and JOSEPH FRENCH, citizens of the United States, residing at Towanda, in the county of Bradford and State of Pennsylvania, have invented certain new and useful Improvements in Stamping and Numbering Machines; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to Which it appertains to make and use the same.

Our invention relates to a power stamping and numbering machine used for imprinting on various articles numbers, letters, and other characters to denote size, style, kind or class, the date of manufacture, a trade-mark, or for the stamping of any other variety of characters that a hand-stamp can be employed to imprint either for designating or for canceling. It is particularly adapted for stamping boots and shoes, although by no means confined in its use to that purpose. As is customary in such machines, the type characters to be printed are formed on the peripheries of disks, which are arranged in series and mounted loosely on a shaft.

Our invention consists in improvements in the operative parts by which the machine is adapted to be driven by any suitable motor;

leaving the hands of the operator free to manipulate the articles to be stamped, in a combined treadle and clutch mechanism by which the printing mechanism may be thrown in and out of engagement with the running mechanism andlocked from operating, in the construction and arrangement of the typedisks and their casing and the manner of setting and transferring the disks, in the arrangement of the type characters for printing, in the means foroperaiing the type-head to give it an upward and downward throw, in means for indicating to the operator the particular characters set or to be set and also for setting them, in means independent of the other setting means for adjusting the position of a separate disk bearing a character out of the regular series, in means for giving the inking-pad a swinging parallel movement under the type-disks and a return movement 50 tothe rear of the same, in the construction of the pad itself, in means for adjusting the contact of the pad with the type-disks, in a Serial No. 683,498. \No model.)

I yielding and selfcom pensatingand adjusting platen, in the particular means for operating the several parts, in the construction of an adjustable spring-clamp, in modifications of a few of the parts, and in improvements of some minor details, all as more fully hereinafter described and particularly claimed.

Our invention is illustrated in the accompanying drawings, in which- Figure 1 is a plan; Fig. 2, a side elevation, partly'in section, showing the parts in position when the article is stamped; Fig. 3, a side interior view showing the type-head and pad in position when the type is inked and the cam mechanism for operating the typehead; Fig. 4, a detail side elevation of the clutch mechanism; Fig. 5, a sectional view of the type-head on line 5 5 of Fig. 6; Fig. 6, a longitudinal central section of the head; Fig. 7, a vertical upright sectional view of the tread le mechanism and platen when lowered; Fig. 8, a detail of a spring-pawl for holding a type-disk when set; Fig. 9, a detail of the type-disk detent; Fig. 10, a modification in detail of means for adjusting the height of the platen; Fig. 11, a section on line 11 11 of Fig. 6, showi ng the lever-controlled type-disk; Fig. 12, a front detail view of the type-head, showing index and other characters and the pointer; Fig. 13, a partly-sectional end view of a modification of the index-pointer on the knob of the type-head shaft; Fig. 14, a detail sectional view of means for regulating the pressure and position of theinking-pad relative to the type-disks; Fig. 15, a front view of the modification shown in Fig. 13; Fig. 16, a section on line 16 16 of Fig. 6; Fig. 17, a detail plan of removable type-head cover; Fig. 18, a bottom plan of this cover, and Fig. 19 a detail section of inking-pad and pad-holder.

Referring to the drawings, A is the frame of the machine, adapted to be secured to a table or other suitable support and carrying at one end an adjustable platen A.

B is the type-head, carrying the type-disks on the endof a vibrating arm 0. The conand type-head are hereinafter more particularly described. This arm at its inner end is hung on a short rocking shaft 0', journaled in standards 0 rising from the frame. The

, arm 0 is provided with a rearwardly-extendstruction and operation of both the platening arm 0", which carries a stud, on the end of which is mounted a roller 0. The roller face 0 engages with a cam 61 on the inner of a cam wheel D. As the cam wheel revolves its action by the cam d is to give to the carrying-arm O and type-head an intermittent up-and-down movement. At the deepest point of the cam when the type-head arm is at its lowest position it is extended horizontally over the frame and platen. The cam-wheel D is keyed on a horizontal shaft E, mounted in standards rising from the frame of the machine.

F is a large cog-wheel, also secured on shaft E, opposite the cam, and meshing with a pinion f, secured on the end of a rear horizontal shaft G, which carries at its opposite end a pulley g, driven by any suitable power.

H is an inking-pad,the specific construction of which, as shown, will be hereinafter described, which is carried at the end of an arm H. The pad is given a reciprocating movement and is supported and carried in a position at all times directly parallel with the type-head characters when the latter are in position to be inked and printed. The pad and its arm are connected to type-head arm C by swinging link-arms h h The link 71 is pivoted at its lower end to a pin h jour naled in one side of the arm H, and its upper end is secured to a short rotating rod cflpassed through the arm 0. The link 7L3 is pivoted at its lower end to a pin h mounted in a short arm 7Z6, extending rearwardly from the pad. At its upper end the link 71 is formed into a head if of the rotating rod 0'.

From its pivotal connection with the links the arm H is bent upward and then extends rearwardly, being formed into a double arm I, comprising two similar sliding members i and t the former integral with the type-arm and each having flattened adjacent surfaces to form a close fit and connected by a pin i and spring-pressed collar 11 at the rearend and a screw-rod at the other end, a slot for the former of these pins, in which it is adapted to move, being formed in the member 2'. Near its rear end the member 5 is provided with a lugj, to which is secured the end of a coiled spring j, seated on the member i and in the hollow of member i its opposite end bearing againsta shoulder of the latter member, thus tending to force it forward. The screw-rod 11" projects through a hollow boss 2' of the member i and a slot of the other member at a forward angle to both and is provided at its lower end with a head bearing against the lower side of member t" and at its upper end with a thumb-nut bearing against the member 01 A guide-keyj on the upper member slides in a slot or groove in the lower member. Member 2' is pivoted at its rear end to a vertical arm K. Turning up the thumbnut slides backward the member '2') on 11 against the spring, and thus carries slightly forward and upward the arm H, and consequently the swinging pad, nearer the typedisks, so as to present a new portion of the inking-surface thereto. Turning the nut in the opposite direction releases the coiled spring, which carries forward the member i and the arm back from the type-head, the relative movement of the members being to lengthen and shorten the double arm I.

In order that the pad shall not scrape along the surface of the type when brought in contact therewith, the pad-box is provided with a spring 1' back of the pad, which permits the pad to yield backward slightly when it strikes the type in its forward and upward movement. This spring is in the cylinder 11 and bears against the head on the pad.

The vertical arm K has at its lower end a journal K, mounted on a stud Z, rigidly secured to the rear extension 0 of arm C. To arm K is secured a rod is, extending rearwardly through an apertured lug 7e on arm G and surrounded by a coiled spring held between said lug and the journal. A roller m mounted on a stud on arm K, is adapted to engage a cam m, forming part of a bracket m, keyed on shaft E, by means of which the arm is reciprocated forward and under the type-head to ink the type. The spring 73 serves to throw the padarm backward and the pad to the rear of the type-head after the type is inked.

The clutch mechanism for throwing the printing and inking mechanisms in and out of connection with the driving mechanism consists of the following means: The bracket m, rigidly secured to shaft E, is provided with an arm m and a short rod m", extending at a right angle from said arm, and on this rod is hung a clutch-pawl 0, having at one end a toe o and at its ogposite or heel end a clutchpawl 0 On the side of the heel the clutchpawl has a pin 0 with which engages the end of a spring 0, said spring being extended back and coiled upon rod on on the bracketarm and its extreme end secured toa smaller pin on said arm. The action of said spring is to hold the tooth of the clutch-pawl into engagement with a cog F within the face of the larger cog F and rigidly secured to or cast on the hub of the latter, whereby when the machine is in operation all the type-operating parts are in gear with the motive power and work together.

P is a rocking lever-bar centrally pivoted on rod p. One end 17 of the bar extends under and is adapted to be pressed down by the platen when the latter is lowered and to be forced up and the opposite end depressed by the action of a spring 19 secured to the under side of the frame of the machine and bearing against the bar. The inner end of the bar is provided with a tooth, against which the end of the clutch-pawl opposite the tooth is adapted to strike in its revolution when the platen is depressed and the inner end of the bar up, the pressure of the bar against this end of the clutch-pawl serv ing to raise the tooth from engagement with ICC thus preserve the face of the type.

the cog-wheel, and thus disconnect the gearing with the cam-shaft. When the end of the bar is carried down by its spring, then the tooth of the clutch-pawl again engages the cog-wheel and the printing and driving mechanisms are connected. To raise the platen, the latter is secured to the top of a hollow standard R and the latter connected to a cap 1' on a rod 7" by a set-screw, which rod in turn is connected to atreadle S. The standard R slides freely through a sleeve R extending down from the base of the machine. The base of the platen is also provided with a steady-pin s, which slides vertically in the frame.

The standard R is internally provided with a coiled spring R and a supporting-rod r within the coil for the purpose of affording a yielding action to the platen under the force of the blows of the type-head and to afford to the platen a self adjusting or compensating action to accommodate it to the use of a greater or less thickness of the article or layers of articles to be imprinted. The platen is also provided with an adjustable springclamp S to hold the articles to be stamped on the platen in front of the type-head and readily adjustable to many variations in the dimensions thereof. It is composed of a casing, which is screwed to the under side of the platen, a series of screw-holes being provided through the top of the platen, as shown, whereby it maybe adjusted in and out to accommodate various sizes of articles to be stamped, and has a clamp-finger and thumb-piece s pivoted to the casing, the heel of the clamp resting against the free end of a spring-bar 8 secured within the casing. The action of the spring is to automatically hold the sheets or layers of articles as they are increased or diminished in thickness, and its employment permits the free use of both hands for other purposes. The platen is also provided with a cushion s fixed on the platen directly beneath the type-head to resist the rigidity and force of blows and to WVe regard this as possessing an advantage over those stamps having the cushion in the plunger-head, as it is a more simple and effective arrangement, in that it obviates any special construction of the plunger-head for the purpose and permits the types to be given a more positive compression, while at the same time it cushions the blow, relieving the types from impact with a solid body. It also to some extent yields to irregular surfaces of some articles to be stamped, thus producing a more perfect imprint.

Y is an adjustable gage for the work, secured by a thumb-screw to the frame of the machine and to the rear of the type-head to gage the distance from the edge of the article to the place of the imprint thereon.

The type-head B is provided with a series of ring type-disks t, mounted loosely on a central hollow shaft T. One end of this shaft outside the head terminates in a knob 25 for turning the shaft and for the consequent turning of the disks separately. Each disk is provided on its periphery with raised letters, figures, or other characters t Between the raised characters each disk is provided with index characters 15 flush with or below the surface of the disk. A single disk used for the purpose hereinafter described is provided with merely a single index character and a corresponding printing character and plain raised portions and recesses on the rest of its periphery. Each disk, except the one last referred to, is also provided with four interior slots i", cut through its edge, encircling the shaft T. The purposes of these various features of the disks are hereinafter described. At the back of the type-head and hung on a single rod so as to turn loosely thereon are a series of spring-pawls 75 one pawl for each disk. The form of these pawlsis shown in detail in Fig. 8. These pawls extend down under the type-disks and engage therewith at their lower sides. Each pawl is provided with a spring-rod 25 which projects above the edge of the type-head. Washers are hung on the pawl-supporting rod between the pawls to permit the free and independent movement of the latter. One disk i is un provided with the interior slots, having a plain inner periphery. This disk carries the character in index and printing type. Secured to this disk is a lever U adapted to rotate the disk on its shaft. A spiral spring 23 connects a projection from the disk i with a rod of one of the spring-pawls. The pawl of the disk adjacent to disk i has a pin tr, engaging an elongated aperture in the pawl of the latter disk, so that when the adjacent pawl is pressed back by its disk the pawl of disk will also be carried back and out of engagement with said disk. The pawl t correspondiug to the disk i is made shorter than the other pawls and is provided with a single abrupt projecting tooth at the end to engage the disk, the middle projection found in the other pawls being dispensed with, whereby the disk t is held firmly from beingdrawn backward byits retracting-spring t when one of its teeth has engaged the pawl-tooth and the disk is held in position for printing.

U is the top or cover of the type-head and is provided on its under surface with a rod u, which when the cover is screwed in place bears against and presses back the spring pawl rods, thus forcing the pawls into engagement with the disks. The top is slotted to allow the lever U to pass throu h and be moved to and fro while. at its rear end it is provided with a projection having a pin on which slides a slotted lever U This lever slides in a slot in the cover and is provided with a pin it to keep it therein. It also has a tooth n at its front part to engage the teeth of the disk adjacent to the disk 25 and having the pawl provided with pin a Attached to the lever U is a curved spring a the rear end of which bears against the link-journals of the type-head and forces the lever out to the end of the slot. The tooth of each pawl rests normally in the recess orspace between two raised characters.

V is a sliding barrel placed within the shaft T. It is given its sliding movementbymeans of a handle V, which is secured to the barrel by means of a screw v The screw 0 passes into the outer end of a rod o and the rod is held in place in the barrel by a collar '0 engaging with a lug in the inner end of said rod. A sleeve surrounds the rod between the end of the barrel and a collar of the rod on its outer end. The handle V is provided with a pointer 9 The barrel near the end opposite to that on which the handle is hung is provided with a slot r. In this slot is placed a detent U (shown in detail in Fig. 9,) having at one end a tooth t and at the opposite end a small curved cross-head c A fiat downwardly-extending spring o is secured to the under side of the detent and bears against the bottom of the slot. The tooth of the detent protrudes above the surface of the barrel through the slot c and the cross head rests in a cross-groove and is flush with the surface of the barrel, being held in its seat by the wall of the hollow shaft T. The detent-tooth is exactly opposite the pointer, and hence engages the same disk to which the pointer points. The shaft T is provided with a longitudinal slot 25 which registers with the slot in the inclosed barrel and through which the tooth of the spring-pressed detent also protrudes. The object of the detent is to engage with the nearest slot in a type-disk and to rotate it when the barrel and disk-shaft are rotated by the knob. It is not necessary that the slots in the several disks should register for this purpose, and the disks may be provided with as many slots as is desired for convenience and rapid work. Four slots being a convenient number, the disks are illustrated with that many, but they may have one or more. The relative positions of the various parts above described in connection with the type-disks are shown in Figs. 5, 6, and 11'.

There is a modification of both the typedisks and their operation and of the adjusting means for the platen, but before their description the operation of the above arrangements will be given.

Let it be assumed that the following characters are to be stamped on a shoe-lining: 10% 13-57678. Before beginning the operation the type-disks are held from turning by their spring-pawls. The pointer g is set opposite a disk having an index-figure l and raised figure 1 upon it. In the arrangement mentioned this is the first disk next to the knob. The placing of the pointer in this position will also carry the detent to the same disk. The disk-shaft, by means of the thumbnut, is then rotated, carrying the detent-barrel with it until the tooth 0f the spring-pressed continues.

detent engages a slot in the disk, whereupon the detent rotates the disk as the turning The turning is continued until the index-figure 1 is under the pointer. When the first index-figure is thus properly placed, the corresponding raised figure 1 will be in a proper position at the bottom of the type-head to be stamped. The pointer is then slid hack to the next disk, carrying back the barrel and the detent to that disk, when the above operation is repeated until the figure 0 is reached and set in place. hen the barrel is drawn along under the smooth portions of the peripheries of the disks, the de tent will be pressed down into the slot. To bring the character 5* into printing position, the leverU is moved forward to the end of its slot, which turns the disk t carrying the index character to the front and the type to its printing position at the bottom of the type-head, in which position the disk will be firmly held by the abrupt tooth of its engaging-pawl. The remaining characters are adjusted as described in the case of the first two numerals. To restore the disk i with the 1% character to its normal position, the lever U having the tooth adapted to engage the disk adjacent to the disk i is moved back, which carries back its engaging-disk. The pawl of this disk is thus forced back, and by means of its pin u engaging the apertured pawl t forces back the latter pawl and releases the tooth ot' the same from engagement with disk i which is thereupon automatically retracted by the spiral spring t. The aperture of pawl is elongated to permit of the free movement therein of the pin a of the adjacent pawl when it is desired to independently adjust the disk of the said adjacent pawl. The character 5- is mounted on a disk of different style from the other characters and provided with a separate setting device, becanse it is the character most frequently used, and the separate disk and setting means therefor permit it to be set in cooperation with any other character with rapidity and convenience and without necessitating the careful rotation and adjustment of a disk bearing several characters.

A modification of the type-head disks and the pointer is illustrated in Figs. 13 and 15. Instead of arranging the index characters on the peripheries of the disks they are placed in circular rows on and around the surface of the knob t employed, as already described, to rotate the disk-shaft and detent-barrel. In this arrangement an additional pointer a is employed, fixed to the frame above the knob. The other pointer on the detent-barrel handle is now employed only to indicate the proper disk having the raised characters to be used; but of course the detent is carried with it to that disk, as before. The indeX characters on the knob are arranged in circular rows, each corresponding to one of the circular sets of characters on the respective disks. The index character on the knob directly under the pointer indicates the disk characterin position for print ing. Since each index character in each row is in lixed relation with the same character on the corresponding disk, it is clear that if there were several slots in the disk the latter might be turned to a diiierentprinting character than that under the knob-pointer. Therefore in setting a character or row of characters by the respective pointers there must be but one slot formed in each disk, so that when the pointer over the knob and the detentand detent-pointer are set to the same character on a particular disk the tooth of the detent must register with and enter the slot in the disk in order to rotate the disk and bring that character to its proper position at the bottom of the type-head for printing.

In operating the modification let it be supposed that the character A is desired to be set and printed. The detent-pointer is slid first to the disk having that character, thus carrying the detent to that disk, and then the knob is turned until the same character appears thereon under the pointer on the frame, whereupon the corresponding printing character will be turned to the proper position at the bottom of the disk, and the same operation is continued with the other characters desired to be printed.

A modification of means for automatically adjusting the platen and engaging the machine with the clutch, and thereby dispensing with the treadle and spring in a standard below the platen, is shown in Fig. 10. It consists of a spring Q, coiled around the same standard R (or another shorter standard may be employed) and confined between the frame and the bottom of the platen, as shown in the same figure, and in the employment of a flexible wire rod 19 connected to the end 13 of the lever-bar P. The lower end of the wire rod may be connected to any suitable footpiece or treadle. The normal action of the spring Q will be to hold the platen up; but it renders the platen elastic and self-adjusting, as in the other form. It constitutes only a somewhat more simple means than the other device.

The operation of the Whole machine is as follows: The driving mechanism being set in motion by connection of the pulley-wheel with suitable power,the type to print the characters desired are set in the manner hereinbefore described and the double arm to which are attached the swinging links of the inking-pad adjusted to the required throw. The platen is then raised by pressure 011 the treadle, and the outer end of arm P being released from the pressure of the platen is forced up by its spring, raising the opposite end of the bar. The inner end of the bar normally contacts with the heel of the clutchplate and prevents its engagement with the cog-wheel of the driving mechanism; but when such contact is removed by the lowering of the end of the bar the clutch again engages the cogs, and the shaft on which the clutch is mounted is turned by such engagement. Rotating this shaft turns the cams mounted thereon, the large cam reciprocating the type-head arm up and down and printing on the articles clamped on the platen at each stroke, while the smaller cam intermittently throws the pad forward to ink the type just before the descent of the arm. When it is desired to reset the type characters or to replace the articles stamped with a new supply, the platen is lowered, whereby the printing and driving mechanisms are disconnected, the latter, however, continuing in motion.

Having thus described our invention, what we claim is- 1.
